Description

Technical Field

[0001] This utility model relates to the technical field of roadbed reinforcement devices, and in particular to a roadbed reinforcement device. Background Technology

[0002] Roadbed reinforcement involves drilling holes to inject cement grout, chemical grout, or other hardening agents into the ground to fill the voids in the soil, forming a reinforced body and thus strengthening the roadbed.

[0003] Patent CN214992762U discloses a roadbed reinforcement device. It includes a support frame with a drilling assembly mounted on it. A drilling drive unit is also mounted on the support frame to move the drilling assembly downwards. The drilling assembly includes a drilling motor, the output shaft of which is fixed with a connecting stud. A telescopic connector is screwed onto the connecting stud, and a drilling component is mounted on the telescopic connector. When using this patent for roadbed reinforcement, as the lifting drive unit moves a lifting plate along a lifting guide rod, the drilling assembly follows the lifting plate along the lifting guide rod, injecting cement slurry, chemical slurry, or other curing agents into the ground. In contrast, the drilling assembly in the aforementioned prior art breaks rocks and soil into fine particles during drilling, which are expelled with the airflow generated during drilling. However, this large amount of dust affects visibility at the construction site and can cause workers to inhale it, potentially leading to respiratory illnesses.

[0004] Therefore, there is a need to provide a roadbed reinforcement device with dust reduction function. Utility Model Content

[0005] In order to overcome the shortcomings of the existing drilling components mentioned above, which break rocks and soil into fine particles during drilling and discharge them with the airflow generated during drilling, but the large amount of dust will affect the visibility at the construction site and cause workers to inhale it, which can easily lead to respiratory diseases, this utility model provides a roadbed reinforcement device with dust reduction function.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a roadbed reinforcement device, comprising a support platform, movable wheels, a limiting block, a drive motor, a lead screw, a sliding plate, an electric push rod, a servo motor, and a drill bit. Four movable wheels are mounted on the support platform, and a limiting block is fixedly connected to the support platform, positioned between the four movable wheels. A drive motor is mounted on the limiting block, and a lead screw is mounted on the output shaft of the drive motor via a coupling. A sliding plate is threaded onto the lead screw, and an electric push rod is mounted on the sliding plate. A servo motor is mounted on the telescopic rod of the electric push rod, and a drill bit is mounted on the output shaft of the servo motor. The device also includes a water tank, a water pump, corrugated pipes, and nozzles. A water tank is fixedly connected to the sliding plate, located behind the electric push rod. A water pump is mounted on the water tank, penetrating the sliding plate. Two corrugated pipes are connected to the water pump, penetrating the servo motor, and nozzles are connected to the two corrugated pipes, positioned above the drill bit.

[0007] To further explain, it also includes a support plate, a hinge rod, and an arc-shaped connecting plate. Two support plates are fixedly connected to the support platform, and a hinge rod is installed on the support plate. An arc-shaped connecting plate is hinged on the hinge rod.

[0008] To further explain, it also includes a fixed plate, a support frame, an electric push rod, and a guide rod. The electric push rod is installed on the support platform and is located behind the limit block. The fixed plate is installed on the telescopic rod of the electric push rod, and the guide rod is fixedly connected to the fixed plate. The support frame is fixedly connected to the electric push rod, and the guide rod slides on the support frame.

[0009] To further explain, it also includes an electric telescopic rod, a telescopic guide rod, and a cleaning plate. The electric telescopic rod is installed on the fixed plate, and the cleaning plate is installed on the telescopic rod of the electric telescopic rod. Two telescopic guide rods connect the cleaning plate and the fixed plate.

[0010] To further explain, it also includes protective pads; protective pads are embedded in both the arc-shaped connecting plate and the hinge rod.

[0011] To further explain, it also includes transparent panels; two transparent panels are embedded in the water tank.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the water pump, the water pump collects water from the water storage tank, and the water is sprayed out from the nozzle through the corrugated pipe, so that the water is sprayed on the upper part of the drill bit, thereby reducing the temperature of the drill bit, reducing wear and extending service life, and effectively binding dust particles together, reducing suspended matter in the air, improving the quality of the working environment, and protecting the health of workers.

[0013] 2. By rotating the arc-shaped connecting plate and placing the grouting pipe on the hinge rod, and then reversing the arc-shaped connecting plate back to its original position, the grouting pipe can be fixed, thereby preventing the grouting pipe from shifting its position during grouting.

[0014] 3. By activating the electric push rod, the telescopic rod of the electric push rod extends, causing the fixed plate and guide rod to move downward, thereby supporting the equipment and preventing the equipment from shifting due to vibrations generated during drilling.

[0015] 4. By activating the electric telescopic rod, the extension and retraction of the electric telescopic rod causes the cleaning plate to move back and forth, and the extension and retraction of the guide rod can clean the ground, thereby making the marking of drilling positions more accurate and preventing debris on the ground from getting stuck in the drill bit.

Detailed Implementation

[0022] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0023] Example 1: A roadbed reinforcement device, see reference Figures 1-4As shown, the system includes a support platform 1, casters 2, limit blocks 3, a drive motor 4, a lead screw 5, a sliding plate 6, an electric push rod 7, a servo motor 8, and a drill bit 9. Casters 2 are symmetrically mounted on the left and right sides of the bottom of the support platform 1 via bolt connections. Limit blocks 3 are welded to the top of the support platform 1, positioned between the four casters 2. A drive motor 4 is bolted to the top of the limit blocks 3. A lead screw 5 is mounted on the output shaft of the drive motor 4 via a coupling. A sliding plate 6 is threaded onto the lead screw 5. A bolt is bolted to the front of the sliding plate 6. The electric push rod 7 has a servo motor 8 mounted on its telescopic rod. A drill bit 9 is mounted on the output shaft of the servo motor 8. The system also includes a water tank 13, a water pump 14, corrugated pipes 15, and nozzles 16. The water tank 13 is fixedly connected to the middle of the sliding plate 6. The water tank 13 is located behind the electric push rod 7. The water pump 14 is installed at the bottom of the water tank 13 by bolts. The water pump 14 passes through the sliding plate 6. Corrugated pipes 15 are connected to both the front and rear sides of the water pump 14. The two corrugated pipes 15 pass through the servo motor 8. The nozzles 16 are connected to the ends of the two corrugated pipes 15 and are located above the drill bit 9.

[0024] See Figure 3 As shown, it also includes a transparent plate 25, with transparent plates 25 embedded on both the left and right sides of the water storage tank 13.

[0025] When roadbed reinforcement is required, the equipment is moved to the designated position by the moving wheels 2. Then, the servo motor 8 is started, and its output shaft drives the drill bit 9 to rotate. Next, the electric push rod 7 is activated, causing its extension rod to move the motor and drill bit 9 downwards to drill a hole in the ground. Simultaneously, the drive motor 4 is started, and its output shaft drives the lead screw 5 to rotate. This causes the lead screw 5 to move the sliding plate 6, electric push rod 7, servo motor 8, and drill bit 9 downwards, allowing the drill bit 9 to drill into the void area inside the roadbed. After drilling is complete, the servo motor 8 is turned off, and the extension rod of the electric push rod 7 is retracted, causing the electric push rod 7 to move the servo motor 8 and drill bit 9 upwards. The output shaft of the drive motor 4 is reversed, causing the lead screw 5 to reverse and drive the sliding plate 6, electric push rod 7, servo motor 8 and drill bit 9 to reset. Finally, the grouting pipe is inserted into the borehole to inject cement. After the injection is completed, the grouting pipe is pulled out. When the drill bit 9 moves downward, the corrugated pipe 15 is stretched. By starting the water pump 14, the water pump 14 collects water from the water storage tank 13. The water is sprayed out from the nozzle 16 through the corrugated pipe 15, so that the water sprays on the upper end of the drill bit 9, thereby reducing the temperature of the drill bit 9, reducing wear and extending its service life. It can also effectively bind dust particles together, reduce suspended matter in the air, improve the quality of the working environment, and protect the health of workers. The transparent plate 25 makes it easy to observe the dosage of water in the water storage tank 13.

[0026] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 and Figure 4 As shown, it also includes a support plate 10, a hinge rod 11, and an arc-shaped connecting plate 12. The support plate 10 is symmetrically provided on the top of the support platform 1 by welding. The hinge rod 11 is installed on the top of the support plate 10, and the arc-shaped connecting plate 12 is hinged on the hinge rod 11.

[0027] See Figure 4 As shown, it also includes a protective pad 24. The upper part of the arc-shaped connecting plate 12 and the hinge rod 11 are both embedded with protective pads 24.

[0028] When cement needs to be injected, the arc-shaped connecting plate 12 is rotated, and the grouting pipe is placed on the hinge rod 11. Then the arc-shaped connecting plate 12 is reversed back to its original position, which can fix the grouting pipe and prevent the grouting pipe from shifting during injection. After the injection is completed, the grouting pipe can be taken out. The protective pad 24 can reduce the pressure of the arc-shaped connecting plate 12 and the hinge rod 11 on the grouting pipe and prevent the grouting pipe from being pinched and damaged.

[0029] See Figure 2 and Figure 5 As shown, it also includes a fixed plate 17, a support frame 18, an electric push rod 19, and a guide rod 20. The electric push rod 19 is installed at the rear of the support platform 1 by means of bolt connection. The electric push rod 19 is located behind the limit block 3. The fixed plate 17 is installed on the telescopic rod of the electric push rod 19. The guide rod 20 is fixedly connected to the middle of the fixed plate 17. The support frame 18 is fixedly connected to the middle of the electric push rod 7. The guide rod 20 slides on the support frame 18.

[0030] See Figure 4 and Figure 5 As shown, it also includes an electric telescopic rod 21, a telescopic guide rod 22, and a cleaning plate 23. The electric telescopic rod 21 is installed on the front side of the fixed plate 17 by bolt connection. The cleaning plate 23 is installed on the telescopic rod of the electric telescopic rod 21. Two telescopic guide rods 22 are connected between the cleaning plate 23 and the fixed plate 17. The two telescopic guide rods 22 are located on the left and right sides of the electric telescopic rod 21.

[0031] Once the device has been moved to the designated position, the electric push rod 19 is activated, causing the telescopic rod of the electric push rod 7 to extend and move the fixed plate 17 and guide rod 20 downwards, thereby supporting the device and preventing it from shifting due to vibrations during drilling. After the reinforcement work is completed, the electric push rod 19 is retracted, causing the fixed plate 17 and guide rod 20 to move upwards back to their original positions. Then, the electric telescopic rod 21 is activated, causing the extension and retraction of the electric telescopic rod 21 to move the cleaning plate back and forth, and the telescopic guide rod 22 to extend and retract, thereby cleaning the ground and making the marking of the drilling position more accurate, preventing debris on the ground from getting stuck on the drill bit 9.
